--- Comment #8 from [email protected] --- Some additional debugging: Still observe glitches when internal and external screen both set to 60Hz. Adaptive sync setting for internal screen doesn't seem to change things (I tried always, automatic, and never) - only using nvidia dGPU through bias setting No glitches, but still crashes when `KWIN_DRM_NO_AMS=1` - forcing sync Setting KWIN_DRM_FORCE_GL_FINISH_MGPU_COPY=1 and KWIN_DRM_FORCE_GL_FINISH_PRESENT=1 No glitches. When `KWIN_DRM_NO_AMS=1`, still crashes. Looking at backtrace, segfault on same line (pageFlipHandler, handling defunct commits). Issue is commit->gpu() is null. - using Nouveau crashes, even when not setting `KWIN_DRM_NO_AMS=1`. In the backtrace, commit->gpu() is null. This does not happen with the commit 03f77c reverted. I think this indicates that the issue is not with the nvidia proprietary driver. - with 03f77c reverted, and https://invent.kde.org/plasma/kwin/-/merge_requests/7980 (commit ad1eb9b215043fafb017a1a3a51790739930d6e0) applied No glitches, and no crashes when setting `KWIN_DRM_NO_AMS=1` -- You are receiving this mail because: You are watching all bug changes.
